Knuckle Boom Cranes
High-Performance Knuckle Boom Offshore Cranes
Knuckle boom cranes feature an articulating “knuckle” joint, allowing for extreme precision, compact storage, and exceptional control. These cranes are specifically designed for complex offshore environments, making them ideal for subsea operations, ship-to-ship transfers, and deep-water vessel integration.
Core Advantages of Our Knuckle Boom Cranes
While engineered for specific payload capacities, our Knuckle Boom models share advanced features designed for dynamic maritime operations:
-
Active Heave Compensation (AHC): Integrated AHC systems maintain loads at a constant depth by compensating for vessel heave motions, which is critical for subsea work.
-
Electro-Hydraulic Power: Driven by robust electro-hydraulic systems to ensure smooth, reliable, and precise lifting in demanding sea states.
-
Multi-Purpose Versatility: Highly adaptable for various services including shipboard handling, offshore ship-to-ship transfers, subsea cargo drops, and certified personnel lifting (man-riding).
-
Extreme Environment Ready: Engineered to operate in harsh climates, with structural design temperatures reaching as low as -15°C.
-
Rigorous Certification: Manufactured in strict compliance with major marine classification societies, including DNV and CCS rules.
